Title: System and method for multicast stream failover
Inventor: HUANG FRANK
IPC: H04L69/40
Filed: 2001-12-28
Abstract: A system and method for avoiding a single point of failure in the broadcast of streaming data. The system uses multiple redundant servers (10, 12) streaming the exactly same data to a failover device (16). The failover device buffers (20P, 20S) the streams into a primary and secondary data stream and automatically switches from the primary to the secondary data stream if it detects a corruption in the primary data stream. Since the buffered data packets of the two streams are identical and are synchronized, there is not outage for multicast receivers when the primary data source fails since there is a switch to exactly the same data in the next packet of the secondary data stream.

Title: Ancre d'outil de puits et methode pour relacher des elements de prehensions
Inventor: DOANE JAMES CHRISTOPHER
IPC: E21B23/01
Filed: 2002-02-28
Abstract: Une ancre l'outil de puits libérant de façon sélective une cage à sabot tubulaire en osier et un manchon de réglage tubulaire dans un assemblage coulissant sur un mandrin tubulaire. La cage à sabot tubulaire en osier est munie d'une pluralité de sabots en osier indépendants. Le manchon de réglage tubulaire est doté d'une surface de glissement conique grossièrement engrenée avec la cage à sabot par une pluralité de pinces s'étendant de la surface de glissement conique dans les engrenages à cran de la cage de sabot. Les pinces sont fixées à l'intérieur des crans pour une bonne adaptation avec les attaches de cisaillement calibrées. Les surfaces de glissement sur les nombreux sabots en osier sont alignées avec la surface de glissement conique pour effectuer un déplacement radial des sabots en osier par une translation axiale du manchon de réglage par rapport à la cage à sabot. Toutefois, aucune translation axiale relative ne peut se produire à moins qu'une force de compression axiale suffisante entre la cage à sabot et le manchon de réglage soit exercée pour cisailler les fixations calibrées. Pour une libération sélective du puits de forage, le manchon de réglage a un jonc d'arrêt assemblé à l'alésage interne du manchon de réglage. Le jonc d'arrêt est muni de filets en dents de scie internes qui s'engrènent avec des filets en dents de scie externes sur le mandrin à une position sélectionnée le long du mandrin. Le déplacement du mandrin pour enclencher les filets du mandrin avec les filets du joint d'arrêt attire la surface de glissement conique de la surface de glissement du sabot en osier libérant ainsi les osiers d'un engagement pénétré avec la paroi du puits.

Inventor: LOU JIN-RONG
IPC: A61M5/32
Filed: 2005-04-20
Abstract: The present invention provides a retractable safety syringe, which comprises a barrel, a sleeve, a connector, a plunger and a standard needle. The barrel is a hollow tube for fitting the sleeve at the front end. The connector is fitted in the sleeve and connected to the standard needle. The plunger is fitted in the rear lumen of the barrel for delivering fluid and retracting the connector with the standard needle into the barrel. The sleeve has twin-twisted threads on its inner surface and is integrated with a ring seal on its rear end by thermal melting. The connector is formed integrally by a cane-shaped cylinder and a tub-body, wherein the tub-body can be engaged with the plunger so as to retract the standard needle with the connector into the barrel by pulling the plunger. In the present invention, the barrel, the sleeve and the connector are separated. In use, the cone-shaped cylinder is tightly held with the standard needle by screwing the standard needle clockwise. Then an injection is performed or a sheath is recapped on the standard needle for a new standard needle replacement. When the plunger is pressed to a full stop of travel, the tub-body of the connector will engage with the plunger. Accordingly, the standard needle connected with the connector can be retracted into the barrel.
